Steam Login issue

hi
I am trying to login in steam using 480 appid, but issues are when I am login in unity editor, it work fine. when I make exe build and run it showing error like below :

[Steamworks.NET] SteamAPI_Init() failed. Refer to Valve’s documentation or the comment above this line for more information.

What I can do?

Please give me a suggestion, I need help to solve this issue.

Thanks, advance.

In the past I’ve had that error until I properly create my game on Steam and use its assigned ID. There’s a text file with that ID you have to put in the build folder until you upload the build to Steam and launch your game from the Steam library.

If I remember correctly, the code comment it says to read says basically this anyway.
